Watching Ray Dalio talk about building his digital twin.

What makes building a digital twin possible isn’t AI. It’s a lifetime of documentation. Books, principles, journals, decisions, mistakes.

I’ve heard Ray speak a few times while at Tony Robbins masterminds, and what stands out every time is how clearly he thinks. That clarity didn’t happen by accident. It came from years of writing things down and refining his thinking.

Here's where it gets interesting. If you document well enough, your thinking doesn't have to die with you. Your great-great-grandkids could have a conversation with you. Not a photo album or a letter. An actual exchange. Generations that would have been forgotten could pass on their learnings, ideas, and memories in a way that's never been possible.

But it all starts with the documentation.

I used to journal constantly. Lessons learned, ideas, what worked, what didn't. Somewhere along the way, I drifted from the habit. I'm picking it back up in 2026.

In a world where AI handles more of the doing, your ability to think becomes the real leverage.
